Recent perspectives on main group-mediated dehydrocoupling of P–P bonds

Abstract

Transition metal-mediated dehydrocoupling is a developing synthetic tool for the preparation of an extensive range of main group element–element bonded species, with broad applications to molecular and polymeric materials. Recent results have stressed the relationship between this class of transition metal reagents and their entirely main group counterparts. But what are the similarities and differences between transition metal and main group systems?
